Crawl Space Repair

Crawl Space Repair and Recovery in IowaCrawl space repair is much needed for many homes built in the United States that suffer from poor moisture management. The current trend of striving for a healthy home is damaged by crawl space moisture. Some of the common symptoms of a crawl space moisture problem are:

  • Mold or moisture damage in the crawl space
  • Musty odors in the living areas
  • Condensation on air conditioning ductwork or equipment
  • Condensation on insulation, water pipes
  • Buckled hardwood floors
  • High humidity in the living area
  • Insect infestations
  • Rot in wooden framing

These symptoms are most often noticed in the humid spring and summer seasons but can occur at any time of the year. Often, the heating and air conditioning contractor is the first person the residents call to deal with the problem. Typically though, the problem is not due to a failure of the air conditioning system; it results from poor moisture control in the wet crawl space and can be solved by waterproofing contractors.

For many decades, building codes have prescribed ventilation with outside air as the primary method of moisture control in crawl spaces. In the humid Spring and Summer, however, ventilation with outside air only makes moisture problems worse. Recent research indicates that a new type of crawl space system, with NO vents to the outside, water drainage and a heavy ground vapor barrier can provide greatly improved moisture control and significant energy savings when properly installed.

Crawl Space Waterproofing Crawl Space Repair for Your Wet Crawl Space

Crawl space waterproofing begins with vapor barriers as your first line of defense against high humidity and poor indoor air quality. These poly crawlspace encapsulation barriers are 10 to 20 mil thick, puncture resistant and made of a high tensile strength material that stops soil moisture from entering the space from the soil. When installed by professional waterproofing contractors, these swimming pool type liners encapsulate the crawlspace so that moisture cannot attack exposed wood and create mold and mildew.

These same crawl space vapor barriers can be used on the basement walls to prevent water and moisture permeation through the wall. By continuing the vapor barrier from the ground up the foundation walls you will create a permanent vapor barrier against most water and water vapor, creating a healthier home environment.

For homes that have extremely wet crawl spaces with possibly even standing water, a drainage system and sump system can be installed prior to the liner being installed to control groundwater. Thus, the crawl space has a water control system in place so the crawl space can be encapsulated without the worry of water seeping onto the liner.

The final steps to waterproofing your crawl space includes sealing vents and dehumidifying the space. Crawl space sealing prevents the humid outside air from settling in the space creating condensation and promoting mold growth. There have been many studies done proving that a sealed crawl space creates a healthier and more energy efficient home due to the elimination of humidity fluctuations, especially when done in conjunction with a dehumidifier in the new controlled air environment.

If the framed area above the crawl space has suffered from structural damage and a loss of stability due to the  high humidity and water vapor transmissions, WCI Basement Repair can also install crawl space support piers to reinforce sagging floor joists and beams.
